It is entirely possible it is one or both of the following;

Ignition timing on the overrun changed to create more airflow while throttle not 'on load',

or,

Position/outlet aspect/shape of exhausts is causing such strange acoustics.

Yes, it was the note on the overrun that it sounded the most noticable difference

I found this technical PDF that looks at all the F1 Season 2010 - Aerodynamic & Mechanical Updates - Version 3
Updated 7th June 2010 includes blown diffusers, very informative and interesting.

..though I think we wil have to wait for version 4 to see details of the latest McLaren updates.
